Description

In films "Pretty Woman" and "Groundhog Day" faces were automatically detected in every 10th frame
using a local implementation of the Schneiderman-Kanade face detector
and rescaled to the uniform scale of 121 by 121 pixels. In the "Open Government" episode of the
"Yes, Minister" situation comedy, face detection was performed on every 5th frame, using the freely
available implementation of the Viola-Jones cascaded detector,
part of the Intel's OpenCV library.
This data set contains a wider variation in pose than the former two. All three sets contain faces with
a wide range of scale, expression and illumination changes, with frequent partial occlusions, see Fig. 1 and 2.
Face images were converted to greyscale by averaging the R, G and B colour channels. A summary is
shown in Fig. 3.
